Fear of the number 13 is known as tridecaphobia, tredecaphobia, or triskaidekaphobia. Persons may fear any situation involving this number, including a house number, the floor of a building, or the thirteenth day of the month. Many buildings omit labeling the thirteenth floor as such for this reason. A phobia can develop for a wide range of objects, situations, or organisms. The list below demonstrates the variety:
